With the development of economic globalization, market competition becomes increasingly fierce, customer diversification of products and individuality more urgent requirements. Market competition is the core of product innovation, product innovation is mainly embodied in the response time to customers and respond to quality. Virtual manufacturing technology is advanced in many fields of knowledge and application integration, which parametric modeling technology, computer simulation technology, analysis and optimization technology, in product design stage or prior to product manufacturing, real-time, in parallel to simulate the products the future of the whole process of manufacturing and its impact on product design, forecasting performance, cost and manufacturability in order to achieve the product development cycle and cost optimization, the maximum efficiency of production purposes. In this paper, both at home and abroad will be on the Virtual Manufacturing Technology Research status and development trend of optical products for the existing design deficiencies, the introduction of virtual manufacturing technology to drive the field of product design category. CD-ROM products in the study design, based on the use of Autodesk Inventor 2009, using parametric design methods, to build a CD-ROM products of the three-dimensional solid model, and virtual assembly, the establishment of a virtual CD-ROM prototype products. Assembly movement using the model of collision and interference detection, verification of the correctness of the model. Finally, the use of Inventor Studio Rendering the model, the effect of the output static map with animated movements.KeyKey words:words: CD-ROM Products ；CAD；Parametric Design；Virtual Assembly；Render； Inventor目 录目 录摘 要 .IAbstract.II目 录.III 第一章 绪 论.1 1.1 本课题的研究背景和意义.1 1.2 CAD 技术的起源和发展 .2 1.2.1CAD 技术的产生及发展过程.2 1.2.2 CAD 系统的构成及分类.3 1.2.3CAD 技术的发展趋势.4 1.3 虚拟装配.6 1.4 本课题研究内容.7 第二章 光驱产品的三维建模.8 2.1Autodesk Inventor 介绍.8 2.2 光驱产品的三维建模.8 2.2.1 托盘进出装置的介绍.11 2.2.2 外壳的介绍.16 2.2.3 内部机构的介绍.18 2.3 本章小结.19 第三章 光驱产品的虚拟装配.20 3.1Inventor 装配环境介绍.20 3.2 光驱的几何约束装配.
